摘要
为利用矿区地球化学数据进行找矿靶区预测,采用了对应聚类分析方法。以山东省平度地区旧店金矿3号脉的实例,说明该方法的实施过程和应用效果。结果表明,该方法以简单步骤和单一图件揭示了在多元地球化学数据中隐藏的核心信息,正确识别了元素含量较低地段的隐伏矿体,为隐伏矿靶区预测探索了一种新的途径。
In order to prognosticate the prospecting targets using geochemical data from mine districts,correspondence cluster analysis is applied.With an example of vein 3 in Jiudian gold deposit,Pingdu,Shandong Province,the simpler procedures and better effects of this method are explained.The results show by single graph that the key information hidden in multivariate geochemical data are exposed,and a target of blind ore body,located in the section with lower element content,are recognized.In brief,a new way to prognosticate the hidden ore bodies is opened up by correspondence cluster analysis.
